Measuring amplifiers with galvanic isolation (potential separation), galvanically separate the input variable of the measuring amplifier from the output variable. Example: A sensor is connected to a machine and is metallically connected to it. The machine is connected to the ground via the ground wire of the power supply. This connection forms the zero potential/reference potential. A measuring card located in a PC is connected to the end of the measuring cable at some distance. The PC is connected there to the supply network and thus to the grounding line at this location, which provides here the reference potential. Due to e.g. different grounding measures, the reference/zero potentials at the machine location and at the measuring PC location may be different. If the reference potentials are different, a compensating current flows to balance the potential differences between these points (ground loop). The voltage difference can be a few volts. This compensating current leads to a falsification of the measurement result. With the help of the galvanic isolation of the measuring amplifier, there is no longer an electrically conductive connection between the sensor on the machine and the measuring PC, the ground connection is interrupted. The potential difference thus becomes ineffective.
Differential amplifier
In principle, the differential amplifier should only amplify the desired useful signal, but suppress the interfering common mode signals. The common-mode signal is generated by the induced coupling of the interference signal into the useful signal. Common mode signals are identical signals with the same phase occurring at both inputs of the differential amplifier. Ideally, these signals are not amplified. The common mode rejection then approaches infinity.
Common Mode Rejection (CMR) is the logarithmic ratio between the differential gain of the wanted signal and the common mode gain, the value is given in dB. The common mode rejection is frequency dependent and decreases with increasing frequency. The measurement error is significantly lower when using potential-separated amplifiers in comparison to differential amplifiers.

How does a carrier frequency amplifier work?
A carrier frequency amplifier is an electronic device used to amplify the carrier signal in a communication system.
The carrier frequency amplifier consists of various components that work together to amplify the carrier signal. These components include an oscillator, an amplifier, a modulator and a demodulator.
First, the oscillator generates a high-frequency carrier wave, which serves as the basis for transmitting information. This carrier wave is then amplified by the amplifier to ensure that the signal can be transmitted over long distances.
The modulator is responsible for modulating the information onto the carrier wave. This is done by changing the attributes of the carrier wave, such as amplitude, frequency or phase, to encode the information.
On the receiver side, the demodulator is used to separate the modulated information from the amplified carrier wave. The demodulator extracts the information by comparing the carrier wave with the modulated attributes and restores the information accordingly.
